One commonly cited argument in favor of blockchain-based smart contracts is that they are unambiguous. By delegating execution to a deterministic program, they leave no room for disagreement about the state of the contract. But this story is wrong. Smart contracts introduce new sources of ambiguity even as they eliminate old ones. The problem is that the result of a computation is a social fact. Bugs, forks, and attacks can cause parties to disagree on what a blockchain-hosted program actually did. The solution is social as well as technical. Modesty about how and why smart contracts work highlights the essential role of blockchain developer and user communities in making them work.
